Examples

Here is a simple asynchronous view that fetches a web page.

from tornado import gen
from django_futures.http_client import HttpClient
from django.views.generic import TemplateView
from core.views import BaseTemplateView

class TestAsyncHttpClient(BaseTemplateView):

    template_name = "test_async_httpclient.html"
    num_client_options = (1, 5, 10, 25, 50, 100)

    @gen.coroutine
    def get(self, request):
        """
        Here we make an asynchrounous web call using the asynchrounous
        aware web client available with Django Futures
        """

        # Go and grab a web page asynchronously
        http_client = HttpClient()

        res = yield http_client.get('http://yahoo.com')
        ctx = {
            'web_response': res
        }

        # Build a Django response
        myres = super(TestAsyncHttpClient, self).get(request, **ctx)

        # In an asynchronous view, we must render a Django response using
        # the render() method of the request object.
        request.render(myres)
    # get()
# TestAsyncHttpClient
